WATER FILTERED SMOKING PIPE Filed Aug. 16, 1965 INVENTOR CHANG PING CHUAN ATTORNEY United States Patent 3,394,710 WATER FILTERED SMOKING PIPE Chang Ping-Chuan, 41 Ting Chuang Road, Yu Feng Li, Pai Ho Cheng, Tainan Hsien, Taiwan Filed Aug. 16, 1965, Ser. No. 482,321 1 Claim. (Cl. 131-173) ABSTRACT OF THE DISCLOSURE A smoking pipe for cut tobacco, cigar or cigarette, is disclosed with a mouthpiece that is removable for storage in a receptacle, and having a filter chamber and smoke circulation path including a liquid bath and a coiled filter path to permit smoke to travel through an elongated cooling path before filtration.

This invention relates to smoking pipes and, more particularly, to those having a liquid bath through which smoke travels.

It has been ditficult to remove enough of the nicotine and tars in tobacco smoke to make smoking safe and enjoyable. Also, hot smoke makes a smoker thirsty. Some smokers prefer tobacco flavored by mint, spices or sugars.

Also, it has been difficult to store or carry pipes with long stems.

Thus, it is an objectof this invention to provide a pipe with improved filtering of smoke.

Another object of the invention is to provide a pipe which provides a smoker with good flavor.

A still further object of the invention is to provide a pipe that is easily stored.

The filter pipe comprises a cylindrical bowl with a mouth for receiving cigarettes or cut pipe tobacco. A path for smoke extends down through a coiled plastic pipe into the bottom of a water bath and then passes through the water, which may be flavored, to a mouthpiece. The water compartment is stopped to prevent water from getting out. The mouthpiece is storable in a socket to lie next to the pipe bowl so that it may be easily stored.

Other objects and features of the invention will be found throughout the specification with reference to the drawings, wherein FIGURE 1 is a section view of a pipe afforded by this invention;

FIGURE 2 is a perspective view of this pipe;

FIGURE 3 is a front view of this pipe; and

FIGURE 4 is a top view of this pipe.

Now with reference to the drawings, the various parts are identified by the following chart:

. Pipe head Pipe casing Mouthpiece Socket for mouthpiece Storage socket for mouthpiece Clipped on pipe cleaner Bowl for out tobacco Smoke chamber J. Water stop valves K. Smoke passage L. Coiled filter pipe M. Liquid Although the pipe is preferably made of plastic, it can be made of wood or metals and have a casing that is decorated, carved or printed. Variations from the cylindrical shape may be made, such as triangular form, for example.

By reference to FIGURE 1, the structure is shown, with a basket-shaped pipe head A, having a receptacle for receiving a cigarette frictionally and a screen for preventing passage of cut tobacco when used as a pipe. The pipe head screws into a socket in casing B and has an extension portion including a smoke chamber H with a throat closed by the floating metal or plastic stopper I if the pipe is turned over or is blown into. This prevents the liquid or water M from spilling.

Smoke flows through passage K into the coiled and water cooled hollow filter pipe L to therein condense and deposit tars and smoke particles. After that it passes through the water M which dissolves more tars, smoke and nicotine. The smoke is thus cooled and filtered to have a good taste.

Mouthpiece C is a bent hollow pipe with four, for example, apertures R for smoke to get through after passing another water stopper chamber I and floating stopper valve P. The mouthpiece C is threaded to alternately screw into screw threaded socket D for smoking or into E for storage next to the pipe casing B.

Sugar or mint may be added to water M for flavoring. Water is simply put into the pipe bowl casing B. To remove the water every two days or so, the pipe head A is unscrewed from the casing to release stop valve J from the throat of chamber H and the pipe casing B may be turned over.

The pipe bowl G has external threads for engagement with complementary internal threads in the upper end of the casing for mounting the same thereon and is adapted to receive cut tobacco therein or one end of a cigarette as shown in dotted lines in FIG. 1.

The metal cleaning stick F may be removed to clean or scrape the pipe bowl G or the interior of the casing B.

What is claimed is:

1. A smokers pipe comprising in combination, a pipe bowl generally disposed about a vertical axis including means for holding and burning tobacco, a passageway at the bottom of the bowl for passing smoke downwardly through the bowl from the burning tobacco, a watertight receptacle compartment disposed beneath said bowl to receive a charge of water below a predetermined water level and retain it in the bottom of the receptacle by the force of gravity, said compartment having communicating structure connected with said passageway to receive and direct said smoke toward the compartment, a hollow pipe coiled to form a helix about a generally vertical axis having one end connected with said communicating structure to receive the smoke and to direct it downwardly toward the bottom of said receptacle compartment and having its other end disposed beneath said water level near the bottom of said receptacle compartment to cool the smoke within a portion of the coiled hollow pipe disposed beneath the water level and to discharge this cooled smoke therefrom at said other end into the water to rise therethrough, a mouthpiece connected with the receptacle compartment disposed above said water level to draw smoke from said bowl to pass through the water, and water stop valve means located above the water level disposed in the smoke flow path between said coiled hollow pipe and said pipe bowl to prevent water from said receptacle compartment from entering the tobacco when water within the receptacle compartment is moved, splashed and tipped.
